I'm assuming that your scenario is based on an enroute hold or something that would amend your clearance limit to the GHI VOR? Remember- you're still "cleared" to your final destination (via your original clearance), it's just that a hold has been placed at the GHI VOR. The EFC determines that time for your to continue, IMHO.
I would continue on the filed/expected routing to the destination airport (or VFR conditions). I would say that you're routing hasn't been changed by the EFC. But what the heck do I know?
3. IFR conditions. If the failure occurs in IFR conditions, or if subparagraph 2 above cannot be complied with, each pilot shall continue the flight according to the following:
(a) Route.
(1) By the route assigned in the last ATC clearance received;
(2) If being radar vectored, by the direct route from the point of radio failure to the fix, route, or airway specified in the vector clearance;
(3) In the absence of an assigned route, by the route that ATC has advised may be expected in a further clearance; or
(4) In the absence of an assigned route or a route that ATC has advised may be expected in a further clearance by the route filed in the flight plan.
